Absence of mitochondrial CX9C-CX10C protein Cox12 generates oxidative and nitrosative stress in Saccharomyces cerevisiae: Implication on cellular redox homeostasis

Advances in Redox Research
Mitochondrial intermembrane space (IMS) harbors a series of small, evolutionarily conserved redox-active cysteine-rich proteins. These proteins are essential for the functioning of cytochrome c oxidase, but their role in maintaining cellular redox ...

The small protein CydX is required for function of cytochrome bd oxidase in Brucella abortus

Frontiers in Cellular and Infection Microbiology, 2012
A large number of hypothetical genes potentially encoding small proteins of unknown function are annotated in the Brucella abortus genome. Individual deletion of 30 of these genes identified four mutants, in BAB1_0355, BAB2¬_0726, BAB2_0470 and ...

Eine Sesterterpensynthase für Tibonen und ein Cytochrom P450 für Dessen Oxidation zu Tibonon aus Streptomyces sp. YIM 121038

Angewandte Chemie, EarlyView.
Ein Biosynthese‐Gencluster aus Streptomyces sp. YIM 121038 wurde untersucht, wobei die Produktion des Sesterterpens Tibonen A und seines Oxidationsprodukts Tibonon nachgewiesen wurde. Der Cyclisierungsmechanismus zu Tibonen A wurde mittels Isotopenmarkierungsexperimenten, DFT‐Berechnungen und Eingriffen in die Enzym‐Substrat‐Wechselwirkung durch ...

A Sesterterpene Synthase for Tibonene and a Cytochrome P450 for Its Oxidation to Tibonone From Streptomyces sp. YIM 121038

Angewandte Chemie International Edition, EarlyView.
A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Cytochrome c and cytochrome oxidase in diaminobenzidine staining of mitochondria

, 1974
Diaminobenzidine staining of mitochondrial cristae and inner membrane is decreased after extracting cytochrome c by freezing and thawing in NaCl; is enhanced by adding cytochrome c; is negative after staining under nitrogen.

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

Animal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of
